Fees for reserved OSS DDoS protection instances (SecReserved)
You are charged based on the number of OSS DDoS protection instances that you purchased and the usage duration of the instances.
You are billed on an hourly basis. Bills are generally generated after a billing cycle ends. The time when bills are generated is determined by the system.
Fees for the remaining duration of OSS DDoS protection instances that are released within the minimum usage duration (SecEarlyReleased)

Fees for API requests protected by OSS DDoS protection instances (SecRequest)
You are charged fees for API requests that are initiated to access buckets that are attached to the OSS DDoS protection instance that you purchased. The fees are calculated based on the number of API requests.
